Description


Updated firefox packages that fix several security issues and one bug are
now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2012-3982, CVE-2012-3988, CVE-2012-3990, CVE-2012-3995,
CVE-2012-4179, CVE-2012-4180, CVE-2012-4181, CVE-2012-4182, CVE-2012-4183,
CVE-2012-4185, CVE-2012-4186, CVE-2012-4187, CVE-2012-4188)

Two flaws in Firefox could allow a malicious website to bypass intended
restrictions, possibly leading to information disclosure, or Firefox
executing arbitrary code. Note that the information disclosure issue could
possibly be combined with other flaws to achieve arbitrary code execution.
(CVE-2012-3986, CVE-2012-3991)

Multiple flaws were found in the location object implementation in Firefox.
Malicious content could be used to perform cross-site scripting attacks,
script injection, or spoofing attacks. (CVE-2012-1956, CVE-2012-3992,
CVE-2012-3994)

Two flaws were found in the way Chrome Object Wrappers were implemented.
Malicious content could be used to perform cross-site scripting attacks or
cause Firefox to execute arbitrary code. (CVE-2012-3993, CVE-2012-4184)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 10.0.8 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Christian Holler, Jesse Ruderman, Soroush Dalili,
miaubiz, Abhishek Arya, Atte Kettunen, Johnny Stenback, Alice White,
moz_bug_r_a4, and Mariusz Mlynski as the original reporters of these
issues.

This update also fixes the following bug:

* In certain environments, storing personal Firefox configuration files
(~/.mozilla/) on an NFS share, such as when your home directory is on a
NFS share, led to Firefox functioning incorrectly, for example, navigation
buttons not working as expected, and bookmarks not saving. This update
adds a new configuration option, storage.nfs_filesystem, that can be used
to resolve this issue.

If you experience this issue:

1) Start Firefox.

2) Type "about:config" (without quotes) into the URL bar and press the
Enter key.

3) If prompted with "This might void your warranty!", click the "I'll be
careful, I promise!" button.

4) Right-click in the Preference Name list. In the menu that opens, select
New -> Boolean.

5) Type "storage.nfs_filesystem" (without quotes) for the preference name
and then click the OK button.

6) Select "true" for the boolean value and then press the OK button.
(BZ#809571, BZ#816234)

All Firefox users should upgrade to these updated packages, which contain
Firefox version 10.0.8 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
